POT3019 High Frequency Power Transformer

Mukugadzirwa kweiyo high-frequency transformer, iyo leakage inductance uye kugovera capacitance yetransformer inofanirwa kudzikiswa, nekuti iyo yakakwira-frequency transformer mukuchinja magetsi inotumira masaini epamusoro-frequency pulse square wave masaini. Mukufamba kwenguva kwekutapurirana, leakage inductance uye capacitance yakagovaniswa inokonzeresa surge ikozvino uye peak voltage, pamwe nepamusoro oscillation, zvichikonzera kurasikirwa kwakanyanya. Kazhinji, iyo leakage inductance ye transformer inodzorwa se1% ~ 3% yeiyo yekutanga inductance. Leakage inductance yeprimary coil-leakage inductance yetransformer inokonzerwa nekusakwana kwakabatana kwemagineti flux pakati pekutanga coil uye yechipiri coil, pakati pematanho, uye pakati pekutendeuka. Distributed capacitance-Iyo capacitance yakaumbwa pakati pekuchinja kwe transformer winding, pakati pepamusoro nepamusoro pezvikamu zvemhepo imwe chete, pakati pemhepo yakasiyana-siyana, uye pakati pemamhepo uye shielding layer inonzi distributed capacitance. Primary winding-Iyo yekutanga mhepo inofanirwa kuiswa mukati memukati-kati, kuitira kuti kureba kwewaya inoshandiswa mukutendeuka kwega kwega kweshanduro yepuraimari inotenderera inogona kunge ipfupi, uye waya inoshandiswa mukutenderera kwese inogona kuderedzwa, iyo inonyatso kuderedza akagovera capacitance yekutanga inomonereka pachayo. Sekondari mamhepo-Mushure mekutanga mhepo yakuvadzwa, zvinodikanwa kuti uwedzere (3 ~ 5) zvidimbu zvekudzivirira jira usati wapepeta mhepo yechipiri. Izvi zvinogona kuderedza capacitance ye capacitor yakagoverwa pakati pekutanga mhepo uye yechipiri mhepo inoputika, uye zvakare kuwedzera simba rekudzivirira pakati pekutanga mhepo uye yechipiri mhepo inoputika, iyo inosangana nezvinodiwa zvekudzivirira uye kupikisa voltage. Bias winding-inga iyo bias winding yakakuvadzwa pakati pepuraimari neyechipiri kana yekunze dhizaini ine hukama nekuti iko kugadziridzwa kweiyo switching magetsi kunobva pane yechipiri voltage kana yekutanga voltage.
